Theory and design of compatible wide range smart temperature sensors in standard CMOS technology is presented. The simulated temperature sensitivity using a CSMC 0.6μm mixed-signal CMOS process is -1. 15μA/℃ (over the temperature range of -40-125℃) and the measured is -0.99μA/℃. The power dissipation of the sensor is 1. 5mW at a 5V voltage supply,and the chip area is 0. 025mm^2. The characteristics of this sensor make it especially suitable for low-cost high-volume integrated microsystems over a wide range of fields, such as automotive, oil prospecting, biomedical, and consumer.
